So Long as your File is saved as Legacy Mesh Format{SaveAs.jpg} and it isnt a
mess of Ngon nastiness there are few if any problems bringing .blend files from
2.64 to 2.49b
Just checked with 2.64 and i can export without doing any
changes{ExportMetric2.49b.jpg}
*(For recent builds Textured Faces must be enabled in Edit Mode 4 proper display
of UV's in 2.49b)

I got a short question. Since 3DS Max refuses to make friends with my PC I was wondering if there will be a new 3ds2kex version for RF7.

Thank you for your answer!

What issues are you having with Max? Also, you can model in a newer version of Blender and export back into 2.49b as long as the newer version isnt using bmesh. I used to model in 2.62 with no issues. I believe 2.63 incorporates bmesh, so I wouldnt go any higher than .62.

This is the wrong thread to be asking this question but to answer your question. NO you cannot fly the Compass Atom 500 in RF6.5. It requires RF7 since it was created with more poly's than 6.5 can handle. You will need to upgrade.

I'm interested in using blender create objects for my RealFlight 7.5 airports. Is export_3ds2kex.py still a viable option? I'm using Blender 2.78. I put export_3ds2kex.py next to export_3ds.py in C:\Program Files\Blender Foundation\Blender\2.78\scripts\addons\io_scene_3d s but didn't get a new export option on blender restart.

Put script here C:\Program Files\Blender Foundation\Blender\.blender\scripts
Download 3ds2kexbeta to somewhere you know where it is,such that you can refer to it's location with Blender2.49b's Scripts Window:Scripts > System > Scripts Config Editor > Export.(See Post #19 in this thread).

Also check Windoze isn't running interference on either "export_3ds2kex.py" script or "3ds2kexbeta" by right clicking on them & checking properties,unblock them if it is.
It works fine on Windows 7 Enterprise & XP.

I am trying to develop a workflow to get an aircraft into RealFlight 8. However, despite using a legacy version of blender (2.45), I cannot get the special .3ds export script to display in File>Export>. Moreover, I do not know whether the compatibility issue that existed in the past is still a problem if I were to use a more recent version of blender. When I tried using the existing .3ds export script and typing the 3ds2kex.exe -v3 -s C:\yourmodeldirectory\test.3ds code appropriate to my file system into command prompt, I got the statement "File has no nodes" rather than the expected output explained in the tutorial. Can anyone help me understand where I have gone wrong, or whether this work flow is still possible on a Windows 10 based platform?
